About discs created on computers
Depending on the application settings and the computer’s environmen-
tal settings, it may not be possible to play certain discs. Record the disc
in a format supported on this unit. For details, contact your application’s
retailer.
If the recording quality is poor due to the disc’s properties, scratches or
dirt on the disc or dirt on the recording lens, it may not be possible to
play the disc.
Creating backup discs
When CD-R/-RW discs are paused or left in the pause mode at cue
points for long periods of time, it may become difficult to play the disc at
that point, due to the properties of the disc. Also, when a specific point
is looped repeatedly an extremely large number of times, it may become
difficult to play that point.
When playing valuable discs, we recommend making backup discs.
